Abstract

EN SITUACIONES DE SOBRECARGA LA PROBABILIDAD DE PERDIDA PARA PAQUETES (D4-D8) DE DATOS ES APROXIMADAMENTE GRANDE EN TODAS LAS COLAS (QU1, QU2) DE ESPERA. LA PROBABILIDAD DE PERDIDA NO ES REGULABLE. LOS PAQUETES (D4-D8) DE DATOS SON ALMACENADOS DE FORMA INTERMEDIA EN MULTIPLES COLAS (QU1, QU2) DE ESPERA LOGICAS, EN DONDE LAS CAPACIDADES DE ALMACENAMIENTO DE UN ACUMULADOR (MEM) DE AMORTIGUACION CONJUNTO SON DIVIDIDAS DE FORMA DINAMICA. LA PERDIDA INEVITABLE DE PAQUETES DE DATOS SE SISTEMATIZA POR MEDIO DEL RECHAZADO OBJETIVADO DE PAQUETES DE DATOS. UN PAQUETE (D6-D8) DE DATOS ALMACENADO EN UNA COLA (QU2) DE ESPERA DE PRIORIDAD INFERIOR SE DESCARGA CUANDO UN PAQUETE (D1) DE DATOS QUE LLEGA DE UNA COLA (QU1) DE ESPERA TIENE UNA COORDINACION DE PRIORIDAD MAYOR Y LA LONGITUD COMPLETA DE LA COLA DE ESPERA HA SOBREPASADO UNA LONGITUD CONOCIDA. ADO DE FORMA SENCILLA UN AMORTIGUADOR CON PROCESOS DE SERVICIO O PROCESOS DE CONTROL DE ACCESO AJUSTABLES, DIFERENTES. CION RAPIDA APROPIADA PARA ATM.
